Application November 29, 1947, Serial No. 788,892

This invention relates to improvements in spinning apparatus and isdirected more particularly to improvements in apparatus for catching andbreaking roving or yarn as it is wound onto a bobbin when the roving orthe yarn is heavier or coarser than desired.

In United States Letters Patent No. 2,428,064, issued to me on September30, 1947, there is shown and described apparatus for use in connectionwith a spinning frame which is adapted to catch and break a roving oryarn as it is wound onto the bobbin, when the roving or yarn is tooheavy or coarse, and the principal object of this invention is theprovision of an improved device for catching and breaking the roving.

With the foregoing and various other novel features and advantages andother objects of my invention as will become more apparent as thedescription proceeds, the invention consists in certain novel featuresof construction and in the combination and arrangement of parts as willbe hereinafter more particularly pointed out in the claims hereuntoannexed and more fully described and referred to in connection with theaccompanying drawings wherein:

Fig. l is a side elevational view of a roving catcher embodying thenovel features of the invention;

Fig. 2 is a perspective view of the control lever of the catcher shownin Fig. 1; and

Fig. 3 is a front elevational view of a plurality of the catchers of theinvention associated with a longitudinal bar.

Referring now to the drawings more in detail, the invention will befully described.

The roving catcher of the invention includes a supporting bracket 2having forward and rear depending spaced arms 4 and 6.

The arm 4 of the bracket may be secured as by bolts 8 to a longitudinalbar [0. Said bar may be such a bar as 26 in the above identified patent.

A catcher I4 is slidable back and forth in the arms 4 and 6 and has ahead [6 on its forward end. A spring l8 around the catcher urges itforwardly and a stop 20 which may be a cotter pin or the like in thecatcher limits forward movements of the catcher.

A look 22 is freely slidable in a guide 24 secured to the bracket 2 andit has an upper head 26.

The member [4 is provided with a seat 28 which receives the lower end 22of the lock 22.

A control lever 30 is pivoted at 32 to the bracket 2 for swinging in ahorizontal plane. The forward end 34 of the lever is adapted to projectbeyond the member 4 and it has a vertical inner 3 Claims. (Cl. 57-107)end part 36 adapted to underlie the head 26 of lock 22.

The upper edge 38 of the part 36 is cam shaped or concave as clearlyshown in Fig. 2. This cam is arranged so that when the central portionof the cam portion underlies the head 26 of the lock the lower end 22 ofthe lock is seated in the seat 28 of the member I4 and holds the saidmember l4 against the action of spring I8 in the rear or retractedposition shown in Fi 1. When the lever 30 is swung in one direction orthe other, the cam elevates the look so that the member i4 is releasedwhereupon it is moved forwardly by the spring 18 to its outer orextended position, shown by dash lines.

With the catcher secured to a support such as ID or some other part of aspinning frame which will locate the catcher adjacent a bobbin, theroving or yarn as it is wound onto the bobbin loops outwardly.

Coarse or heavy yarn loops outwardly to a greater extent than relativelylighter or finer yarn.

The coarse yarn strikes the end 34 of the control lever to swing it sothat the cam 38 of arm 36 elevates lock 22 whereby the catcher isextended by the spring I8. Then the heavy yarn catches on the member l4and is broken as is desired.

By swinging the control lever to its normal position, the member 14 maybe moved inwardly so that the lock 22 drops into the seat 28 to hold thecatcher in retracted position.

The invention may be embodied in other specific forms without departingfrom the essential characteristics thereof. Hence, the presentembodiments are therefore to be considered in all respects merely asbeing illustrative and not as being restrictive, the scope of theinvention being indicated by the appended claims rather than by theforegoing description, and all modifications and variations as fallwithin the meaning and purview and range of equivalency of the appendedclaims are therefore intended to be embraced therein.

What it is desired to claim and secure by Letters Patent of the UnitedStates is:

1. A yarn catching and breaking device for a spinning machine comprisingin combination, a support for securing to a spinning machine, a catcherslidable back and forth in said support between forward breaking andrear positions, means urging said catcher to breaking position, lockmeans slidable in said support engageable with means provided on saidcatcher to releasably hold said catcher in rear position, and means 3swingable on said support to release said lock means and adapted to beengaged by yarn for swinging to act on and release said lock means.

2. A yarn catching and breaking device for a spinning machine comprisingin combination, a support for securing to a spinning machine, a catcherslidable in said support between forward yarn catching and rearpositions, a spring urging said catcher to forward position, and meansholding said catcher in rear position,'said means inwhereby said catcheris urged forwardly by said 15 spring. Y

3. A yarn catching and breaking device for a spinning machine comprisingin combination, a support for securing to a spinning machine, a catcherslidable in said support between forward yarn catching and rearpositions, a spring urging said catcher to forward position, a lockslidable in said support between locking and non-locking position, saidcatcher having a seat therein which said lock is receivable when in rearposition whereby said catcher is held in rear position, a leverswingable on said support adapted to be engaged by yarn and engageablewith and adapted to move said lock to non-locking position.
